Today we write out 99 in Roman numerals as XCIX because XC = 90 and IX = 9. Therefore it logically follows that XC+IX = XCIX as in the case of Hindu-Arabic numerals. But the Roman numeral system does not contain a zero figure for positional place value purposes. Instead the Romans most probably worked out 99 as IC because:-
XC is a simplification of LXXXX
IX is a simplification of VIIII
So LXXXX+VIIII = LXXXXVIIII and by placing I to both sides of these numerals they can be simplified to IC in fact the Latin word for IC is 'undecentum' which literally means one from a hundred.
MCMXCIX From left to right [ M ] [ CM ] [ XC ] [ 1X ] [1000] + [1000 - 100] + [100 -10] + [ 10 -1] 1000 + 900 + 90 + 9 =1999 M = 1000 C = 100 X = 10 1 = 1
It means that M is to be multiplied by a thousand giving it a value of 1,000,000 Sometimes it is in brackets like (M) but this also means muliplication by a thousand
100x - 89x = 110 ∴11x = 110 ∴x = 10 In more detailed explanation; The first line means "100 times x minus 89 times x equals 110" We can apply the distributive rule here. Both "100x" and "89x" are divisible by x. This means we can factor it out of both terms giving us the expression: x (100 - 89) = 110 We can then subtract 89 from 100, giving us: x(11) = 110 or: 11x = 110 Finally, both sides are divisible by 11, so we can divide it from both sides, giving us: x = 10
Advantages of using Roman numerals: In outlines, you can differentiate between indented subsections, giving more clarity to an outline. It is harder to misinterpret a number if the number is smudged in writing.Disadvantages: There is no "zero" in Roman numerals. They are much harder to add and subtract, especially in numbers greater than ten. The hindu-arabic numbering system is more succinct (for example, the year "1988" in Roman numerals is "MCMLXXXVIII". The largest number that can be expressed properly in Roman numerals is 3,999,999 as MMMCMXCIXCMXCIX (the bolded characters would have a line over them.
